使用 Jest 运行测试套件时,我遇到了要求我更新包的警告:
npm WARN deprecated jest-dom@2.1.1: jest-dom has moved to @testing-library/jest-dom. Please uninstall jest-dom and install @testing-library/jest-dom instead, or use an older version of jest-dom. Learn more about this change here: https://github.com/testing-library/dom-testing-library/issues/260 Thanks! :)
npm WARN deprecated react-testing-library@5.9.0: react-testing-library has moved to @testing-library/react. Please uninstall react-testing-library and install @testing-library/react instead, or use an older version of react-testing-library. Learn more about this change here: https://github.com/testing-library/dom-testing-library/issues/260 Thanks! :)
在package.json文件中,我更改了以下内容:
"jest-dom": "^2.1.1",
"react-testing-library": "^5.3.0"
to
"@testing-library/jest-dom": "^5.11.1",
"@testing-library/react": "^10.4.7"
当然,还有来自于的导入语句
import "jest-dom/extend-expect";
to
import "@testing-library/jest-dom";
我替换了旧的内容并添加了新的,但我在Semaphore CI中执行测试时遇到了多个错误导致测试失败(而在我的本地机器上没有出现这些问题)。
FAIL src/redux/actions/tests/myActions.test.js

Jest encountered an unexpected token
This usually means that you are trying to import a file which Jest cannot parse, e.g. it's not plain JavaScript.
By default, if Jest sees a Babel config, it will use that to transform your files, ignoring "node_modules".
Here's what you can do:
• To have some of your "node_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config.
• If you need a custom transformation specify a "transform" option in your config.
• If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option.
You'll find more details and examples of these config options in the docs:
https://jestjs.io/docs/en/configuration.html

我不是前端开发人员,因此很高兴听到需要哪些更多信息来帮助。非常感谢!
